I just built a computer with this board using a AMD x2 4450e cpu, GSkill DDR2 800 PC2-6400 memory .. i just noticed in CPU-z my DRAM Frequency is 385. Mhz. where it should be 400 .. i just found out how to get to DRAM settings with ctrl-F1 keys.. but i think i need to adjust dividers in order to bring it up to 400mhz
 
And i can't find that area.. anyone know how to get there?
 
Thanks..

It's in the manual usually.

Section 2-7
M.I.T.
CPU Frequency
CPU Clock Ratio
